Wireless sensor 5 common problems and solutions

After the wireless sensor is installed, the display may be displayed in batches or the number is inaccurate. Solution: The performance of the product selected by the customer does not meet the on-site conditions. The transmitter with isolation function needs to be installed or replaced.

1. After the wireless sensor is installed, the display may appear in batches or the number is inaccurate.

Cause: There is electromagnetic interference at the site, or the same line slot where the signal line and the power line go.

Solution: The performance of the product selected by the customer does not meet the on-site conditions. The transmitter with isolation function needs to be installed or replaced.

2, wireless sensor installation, display error or not displayed

Cause: The signal line is positive or negative wiring error.

Solution: Disconnect the power supply, swap the positions of the two signal wires, and press the terminals to re-power them. In particular, the PT100 thermal resistance sensor with a three-wire output without a transmitter often has such problems when installed on site.

3. The value displayed by the wireless liquid level sensor after use is unchanged.

Cause: Water in the air duct

Solution: Return to the factory for maintenance, drain the water in the airway, re-calibrate the meter, and use.

4, the temperature sensor has no signal output

Reason: When the worker is installed, because the sensor is not known, the force is too large, causing the pin of the temperature measuring component to be pulled out completely, so that the signal loop is interrupted.

Solution: When installing, simply connect the wires to the terminals, without removing the transmitter or magnetic plate, and press the signal leads with the terminals.

5, the intelligent control instrument installation does not display

Cause: The instrument parameter settings are incorrect.

Solution: First confirm the type of signal that the wireless sensor is connected to, and adjust the input parameters of the intelligent control meter corresponding to this type.

LED Switches

LED Switches

LED Switches, belong to LED Light Switches serious, is also called flat-reset LED indication switch. The overall appearance of the product is a flat panel type, and can be automatically reset. The switch function part has an LED indicator, which not only accurately indicates the on/off state of the switch, but also makes it easy for the user to find the switch position in the darkness.


LED Light Switches


LED Push Button Switches are suitable for consumer products, computer products, test instruments, communication equipment. This light switch could contain momentary switches and self lock and it is very sensitive. It could work only with a little strength, just a bit like Micro Switches . Furthermore, the shape of the light could be round, square and five position as well. In addition, we could equip with all kinds of color for the LED On Off Switch, including white,yellow,red, green,etc. One more important advantage for our light switch is that we could equip with double color for the LED light switches,like red&green, red&blue, red&yellow.


mini push button switches


Different from other switches,including Metal Switches, Rotary Switches, Slide Switches, Automotive Switches, LED switches is a flat design with no rocker protruding parts. The style is modern and fashionable,not easy to dust. Its opening and closing operations are all in the same position. After the release of the hand, the rocker automatically restores the flatness and feels better and lasts longer.
